Abstract

The invention discloses a laser standard scribing method for a low-speed diesel engine frame for a ship. An upper plane, a middle plane and a lower plane are arranged out of the frame; and multiple frontal guide boards symmetrically and uniformly distributed and side guide boards perpendicular to the frontal guide boards are longitudinally arranged in the frame. The method is characterized in that a laser ray is set as a measurement reference line; and an upper plane processing line, a middle plane processing line, a lower plane processing line and a longitudinal center line and a transverse center line, serving as processing positioning reference lines, of the frame are once scribed in the frontal positions of the frame to guarantee the uniformity of processing allowances of the upper plane, the middle plane, the lower plane, the frontal guide boards and the side guide boards. The method achieves the effects of automatic alignment of the reference lines, low labor intensity, high measurement precision, high working efficiency and low potential safety hazard, realizes once completion of allowance detection and scribing of such processing parts as the upper, middle and lower planes, the frontal guide boards and the side guide boards of the frame in the frontal positions of the frame, and is suitable for the scribing operation of large diesel engine frames and large parts.

Description

technical field [0001] The invention relates to a manufacturing process method for large diesel engine parts, in particular to a laser reference marking method for a marine low-speed diesel engine frame, and belongs to the technical field of diesel engine manufacturing. Background technique [0002] The frame is one of the important parts of a large low-speed marine diesel engine. It is a welded structural part. After assembly, the frame is associated with many parts. and other moving parts. see figure 1 , there are upper plane B2, middle plane B3, lower plane B1 and door frame B6 on the frame, refer to figure 2 , along the longitudinal (X-X direction) rack inner cavity, a series of evenly spaced, parallel to each other and perpendicular to the longitudinal centerline X-X transverse partitions are arranged, and the two ends of each transverse partition are provided with symmetrical guide plates about the longitudinal centerline X-X, Each pair of guide plates has a positi...
